Description

TECHNICAL FIELD

The present invention relates to a data carrier according to claim 1, to a secure article comprising or consisting of such a data carrier according to claim 14, and to a method of producing a data carrier according to claim 15.

PRIOR ART

Data carriers such as smart cards or electronic tags for passports, as payment cards for payment transactions, etc. are well-known in the art. Such data carriers can provide an identification or an authentication such as a light emission indicating a successful payment transaction to the owner of the data carrier. For this purpose, a light-emitting device such as an LED module can be provided, which emits light when the payment transaction is successful. In order for the light emitting device to emit light, it needs to be powered.
To this end it is known to provide an LED antenna that powers the LED module. Disadvantages associated with such an LED antenna are the high number of turns required on the LED antenna in order to power the LED module, a big energy consumption, and perturbations of other antennas in the data carrier such as the antenna of an electronic module. Furthermore, such an LED antenna is associated with manufacturing costs and the LED lightning is weak.
Other known solutions, where an LED module is turned on without any other energy than the energy from a reader field requires semiconductors that are provided in addition to an antenna, which thus requires additional components and is associated with manufacturing costs as well.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a data carrier comprising a light emitting device that is of a simple design and that exhibits lighting capabilities wherein perturbations are minimized.
This object is achieved with a data carrier according to claim 1. That is, a data carrier for a secure article is provided, wherein the data carrier comprises at least one electronic module, at least one first antenna, at least one second antenna, and at least one light emitting device. The first antenna is coupled to the electronic module. The first antenna is configured to communicate with a remote device being arranged remotely from the data carrier. The electronic module is configured to communicate with the remote device via the first antenna. The second antenna is configured to communicate with the remote device, and wherein the second antenna powers the light emitting device upon a communication of the second antenna with the remote device.
The electronic module particularly preferably is a commercially available electronic module. The electronic module preferably comprises an internal microprocessor chip and optionally one or more contact pads. The contact pads may be conventional contact pads such as contact pads being used in contact-type smart cards and being configured to establish an electrical contact with a remoted device being a contact card reader, for instance. Such a smart card is commonly referred to as dual interface smart card. However, it is likewise conceivable that no contact pads are present and that the data carrier is a contactless smart card. That is, the contact pads can be contactless pads and/or contact connection pads.
The first antenna being configured to communicate with the remote device means that the first antenna can establish a communication with the remote device via a physical connection or via a contactless connection. A physical connection is preferably established by means of a wired connection. A contactless connection is preferably established via a field of action of the remote device. Likewise, the second antenna being configured to communicate with the remote device means that the second antenna can establish a communication with the remote device via a physical connection such as a wired connection or via a contactless connection such as via a field of action of the remote device.
Hence, the electronic module can have a function of a contact type and of a non-contact type and can thus be a so-called combi module. However, it can likewise have a function of non-contact type only and be a so-called contactless electronic module.
In the event of the data carrier being a smart card the smart card can thus be a so-called dual interface smart card or a contactless smart card. In addition, various types of such smart cards are conceivable. For instance, the smart card can be a full or combi card, a metal card, a biometrics card, etc.
The first antenna and/or the second antenna preferably correspond to a wire, particularly preferably an electrically conductive wire such as a copper wire.
Since the second antenna powers the light emitting device upon its communication with the remote device, the present invention simplifies the design of the data carrier since no additional electronic elements such as additional resistance or capacitances are required. Moreover, the absence of such additional electronic elements results in an absence of perturbations of the communications established by the data carrier. In particular, any frequency properties of the first antenna and of the second antenna of the data carrier are not modified.
Hence, the communication between the first antenna with the remote device and/or of the second antenna with the remote device preferably is a wireless communication via electromagnetic radiation, in particular via radio waves. As such, the remote device preferably is configured to emit electromagnetic radiation, in particular radio waves. The remote device particularly preferably corresponds to an RF reader as it is known in the field of the art. Consequently, it is preferred that the first antenna and/or the second antenna is in each case a radio-frequency (RF) antenna and/or that the electronic module is an RF module. Said RF module, when being associated to the first antenna, can also be referred to as an RF transponder.
The light emitting device is preferably configured to be powered by the second antenna upon the communication of the electronic module with the remote device via the first antenna. However, the light emitting device can likewise be configured to be powered by the second antenna in the absence of a communication of the electronic module with the remote device.
That is, the light emitting device can be powered on when the second antenna is exposed to a field of action of the remote device whether or not there is a communication established between the electronic module and the remoted device. In particular, the light emitting device is preferably configured to be powered with lower energy than the electronic module.
The second antenna is preferably configured to power the first antenna upon the communication of the second antenna with the remote device.
That is, the second antenna is preferably configured as a booster antenna that enhances or improves the communication between the first antenna and the electronic module with the remote device. In other words, in the event of the first antenna being associated to the electronic module and thus forming a transponder, the second antenna can be seen as a booster antenna for said transponder. Hence, the second antenna can serve a dual function, namely it can power the light emitting device as well as the first antenna.
The second antenna and the first antenna are preferably inductively coupled to one another.
To this end it is conceivable that the second antenna comprises a coupling area, and wherein said inductive coupling between the second antenna, or booster antenna, and the first antenna is preferably established at the coupling area of the second antenna. The coupling area of the second antenna preferably corresponds to a spiral comprising one or more turns that is formed by the second antenna in the form of the wire. Said spiral or coupling area is preferably arranged in view of the first antenna in order to enhance the inductive coupling. However, it should be noted that said coupling area is not needed for the establishment of the inductive coupling and is a purely optional feature.
The second antenna is preferably physically connected to the light emitting device.

To this end it is particularly preferred that the first spiral and the second spiral constitute a single-piece component, i.e. form part of a single-piece second antenna. In other words, the end portions of the first and second spirals are not structural or physical end portions such as free ends of separate wires.
